Yes I'm satisfied with one LL segment for reasons a, c, and e.
a- I did femurs and lengthened 8 CM, the max amount the rod can lengthen. 8 CM is a huge gain, I went from 5'9 to 6'0. I went from just below average height to tall (in the US). In a room full of people, I went from blending in the crowd as average to being one of the tallest people in the room. I went from my height being a bit of a negative physical attribute to a positive asset in the context of both dating and career workplace dynamics. Most importantly, I went from a guy who had anxiety and negative thoughts about his height on a daily basis (wore shoe lifts every day) to living a life where I don't even think about height anymore. I'm very satisfied with my height and have no desire to get taller. Sure, 6'2 or 6'3 would be even better, but I have no desire, 6ft is more than enough, and any additional height beyond 6 ft diminishes in value IMO.
c - The biggest cost of LL was not money, it was time. I gave up 4 months of my life for this (so far, I'm still consolidating and I won't return to "normal" life until 6 months), where my career, family, and friends were set aside and I dedicated myself to LL. Life is short. Time is precious. 6 months is a huge chunk of time. I wouldn't do LL again because the cost in time is too large, even if someone did it for free, I'd say no. I simply want to get back to living my life again.
e - My goal was to keep LL private. Going from 5'9 to 6 ft is going to shock a lot of my friends and family. Thankfully I've been wearing 2 inch shoe lifts for the past 5 years that I plan on throwing out, so I'm hoping most won't notice. However if I did another 2 or 3 inches in a second LL procedure it would definitely be painfully obvious that something is very off about me.
